Bariatric Diet:
Our Proven 90-30-10 Nutrition Plan
Introduction
Bariatric surgery is one of the most effective treatments for obesity, but surgery is only one part of your success. Long-term weight loss depends on developing healthy eating habits that nourish your body while protecting your surgical results.
At Weight Loss Team in Puerto Vallarta, Mexico, every patient receives personalized nutritional guidance built around our 90-30-10 Bariatric Diet. This simple approach helps patients prioritize protein, limit carbohydrates, and reduce added sugars to support steady weight loss and long-term health after Gastric Sleeve Mexico, Gastric Bypass Mexico, SASI Bypass, or Revision Bariatric Surgery.
The 90-30-10 plan is easy to remember:
- 90 grams or more of lean protein every day
- Less than 30 grams of total carbohydrates daily (not net carbs)
- Less than 10 grams of sugar per day
This nutritional strategy encourages patients to focus on nutrient-dense foods while minimizing highly processed carbohydrates and sugary products that can slow weight loss or contribute to weight regain.
What Is the 90-30-10 Bariatric Diet?
The 90-30-10 Bariatric Diet is the nutritional foundation we recommend for long-term success after bariatric surgery.
90 Grams of Lean Protein
Protein is the cornerstone of every meal because it helps:
- Preserve lean muscle during weight loss
- Support healing after surgery
- Increase fullness
- Reduce hunger
- Maintain metabolism
- Support healthy hair, skin, and nails
Protein should always be eaten first at every meal.
Less Than 30 Grams of Total Carbohydrates
Our program focuses on total carbohydrates, not “net carbs.”
Many products marketed as “low-carb” subtract fiber or sugar alcohols to calculate net carbs. For our patients, we recommend tracking total carbohydrates because this provides a simpler and more consistent way to manage carbohydrate intake.
By limiting total carbohydrates, patients often find it easier to:
- Control hunger
- Improve blood sugar stability
- Reduce cravings
- Support continued fat loss
Note: it is so important to make sure what you eat does not have Carbs, for example fruit has a lot of carbs and sugars! We recommend you use an app on your phone to see what carbs are in whatever you plan to eat!
Less Than 10 Grams of Sugar Per Day
Added sugars provide calories with little nutritional value and can interfere with weight loss goals.
Keeping sugar below 10 grams per day encourages patients to choose whole, nutrient-rich foods instead of sweetened beverages, desserts, and processed snacks.
Why Protein Comes First
Following bariatric surgery, your stomach holds much less food than before. Every bite matters.
Lean protein should be the priority at every meal because it helps your body:
- Heal after surgery
- Preserve muscle
- Stay satisfied longer
- Support immune function
- Promote healthy metabolism

Following the 90-30-10 Plan After Surgery
Gastric Sleeve Mexico
Patients who undergo gastric sleeve surgery benefit from focusing on protein-first meals while gradually progressing through the post-operative diet stages. The 90-30-10 approach provides a simple long-term framework once regular foods are reintroduced.
Gastric Bypass Mexico
Because gastric bypass changes nutrient absorption, patients also need lifelong vitamin supplementation and regular follow-up in addition to following the 90-30-10 nutrition goals.
SASI Bypass
The SASI Bypass combines restrictive and malabsorptive components, making adequate protein intake especially important. Our nutrition team provides individualized recommendations to ensure patients meet protein and hydration goals while maintaining balanced nutrition.
Revision Bariatric Surgery
Patients undergoing revision surgery often benefit from revisiting healthy eating habits. The 90-30-10 plan provides a structured, sustainable approach to support renewed weight loss and long-term maintenance.

The 90-30-10 program uses total carbohydrates because they provide a straightforward and consistent way to track carbohydrate intake without relying on different "net carb" calculations that vary between products.
We do not recommend eating fruit in the bariatric diet during the weight loss phase and if fruit is eaten you must make sure it fits in both the sugar and carbohydrate macro of the 90-30-10 goals.
Ninety grams is the minimum daily target in our program. Some patients, particularly those who are larger, more active, or further along in recovery, may benefit from higher protein intake based on individualized recommendations. The larger amount of protein you eat in a day the faster you will lose weight.
While the plan was developed to support bariatric patients, the principles of prioritizing lean protein, limiting refined carbohydrates, and reducing added sugars can also support healthy eating for many individuals. Dietary needs should always be discussed with a qualified healthcare professional.
